Description

Connector and method for manufacturing the same}

The present invention relates to a connector and a method of manufacturing the same, and more specifically, to a connector that can be provided on a board and a method of manufacturing the same.

Generally, connectors are provided in various electronic devices for electrical connection. For example, connectors are installed in electronic devices such as mobile phones, computers, tablet computers, etc., and can electrically connect various components installed in the electronic devices to each other.

22 is a plan view of a conventional plug connector and a receptacle connector. These conventional plug connectors 30 and receptacle connectors 40 have predetermined insulation properties and are arranged side by side with each other along one direction on the insulating bodies 31 and 41 placed on the substrate. It consists of a plurality of contacts 35 and 55.

In general, the insulating bodies 31 and 41 include flat bottom portions 32 and 42 and a pair of support wall portions 33 and 43 that protrude upward from the bottom portions 32 and 42 and extend parallel to each other. The plurality of contacts 35 and 55 described above are arranged and coupled to a pair of support wall portions 33 and 43 in a row along their extending direction.

At this time, as a way to increase the number of contacts 35 and 45 of the plug connector 30 or the receptacle connector 40, the size of the insulating bodies 31 and 41 on which the contacts 35 and 45 are placed is increased. Alternatively, it may be considered to densely arrange the contacts 35 and 45 on the insulating bodies 31 and 41 by narrowing the distance (i.e., pitch) between the contacts 35 and 45. .

However, when the first of the above-described methods is applied to the conventional plug connector 30 or the receptacle connector 40, as the number of contacts 35 and 45 increases, the size of the insulating bodies 31 and 41 becomes excessive. Since it can be long or large, the freedom of circuit design is limited, manufacturing defects may occur due to bending of the insulating bodies 31 and 41, and the overall strength of the plug connector 30 or receptacle connector 40 may be reduced. There is a problem that can be lowered.

When the second of the above-described methods is applied to the conventional plug connector 30 or the receptacle connector 40, as the parts where the neighboring contacts 35 and 45 are mounted on the board become closer to each other, the two contacts 35 and 45 ), there is a problem that a short circuit may occur because the insulation performance between them is not secured.

Accordingly, there has been an urgent need to develop a connector that can minimize the pitch (p) by arranging a plurality of contacts 35 and 45 in a limited space without causing the problems with insulation performance and short circuit described above.

Meanwhile, a connector may be configured so that different types of contacts with different shapes are arranged in a row on an insulating body. For example, first contacts having a first shape may be arranged in a row on a pair of support wall portions, and second contacts having a second shape may be arranged between neighboring first contacts.

However, according to the conventional connector manufacturing method, in order to manufacture a connector in which different types of contacts are arranged in a row as described above, the first carrier to which the first contact is connected and the second carrier to which the second contact is connected are arranged to face each other. After that, a process of forming the supporting wall portion of the insulating body must be performed.

At this time, the insulating body of the connector generally has a pair, that is, two support walls arranged side by side. Therefore, according to the conventional connector manufacturing method, the process of forming the support wall portion must be performed twice to individually form a pair of support wall portions, and then a process of coupling the pair of support wall portions to each other must be performed. This problem complicates the connector manufacturing process and increases the connector manufacturing cost.

Accordingly, there has been an urgent need for the development of a connector manufacturing method that can simply and quickly manufacture a connector in which different types of contacts are arranged in a row on a pair of support walls, respectively, through a single insulating body forming process.

The present invention was conceived in consideration of the above points, and the purpose of the present invention is to provide a connector capable of minimizing the pitch between contacts and a method of manufacturing the same.

Another object of the present invention is to provide a connector that can be electrically connected (or in contact) with other connectors with high stability and a method of manufacturing the same.

Another object of the present invention is to provide a connector with strong rigidity (or strength) and a method of manufacturing the same.
